This invention relates toa fountain brush for use iii forming charactersand particularly for writing the Chinese language ant the object of myinventionis to provide such a fountain brush of few` parts and onewherein the ink will not How readily except when the brush is in use. Y

Another object of my inventionV is to provide means in a fountain brushwhereby the bristles will notl become dry and stift when the brush isnot in use. u

Another object of my invention is to locate an auxiliary ink reservoirin such position in a fountain brush that an immediate supply for theflow of ink to the bristles will b e provided when the brush is put touse.

I accomplish the above and other objects of my invention, which will beapparent as the description proceeds,'by means of the device shown inthe accompanying drawings, in whichf Figure l is a perspective of myfountain brush with the cover in position thereon;

Figure 2 is a perspective of the brushV with the cover element thereofshown in section;

yand l Figure 3 is a viewl of the brush with the main parts thereofshown in section.

In the drawings, in which like characters indicate like parts on all thefigures thereof, l indicates the holder for the ink reservoir 2. The inkreservoir 2 is preferably formed being fitted over a reduced portionofthe tube 3. .The tube 3 .is preferably formed from a hard rubbersubstitute and serves "as a distending and holding means for the ofmetal. The-conductor 6`is provided with a small aperture in its lowerextremity, which acts as an air inlet and an inky outlet for the inkreservoir.

Surrounding the tube 5 and forming` a continuation of the tube 3 is'anelongated tube 7 formed from the same material as that comprising thetube 3. The upper extremity of the tube 7 is provided with screw threadsof the same pitch as those lof the vwith the tube`7. of thin rubber,thelower open end thereof tube 3. ,The` holder 2, being provided wit-h i lsuitable cooperating internal screw threads, thus serves as a means forholding the parts 3, 5 and 7V in proper relation to each other.

Mounted in the lower end of the tube 5 are.

suitable bristles 8 which comprise thewriting element or characterforming means of the device; The bristles 8 surround a hollow metal tube9 by means of which the ink is conducted to the bristles during use. Theopening through thetube 9 is of minute cross section'whereby the inkwill be fed in small quantities to the bristles, thus avoiding danger ofthe brush flooding or dropping ink.

During the use of the brush as a writingV instrument, the conductor 6and the tube 5 belowthe conductor fill with ink, the ink passingthroughthe aperture in the lower part of the conductor to the tube 9 throughwhich it flows to the bristles.

Even wlien'tlie pen is not in use, the ink remains in the tube 5 belowthe conductor 6, thus keeping the bristles moist and preventing theirbecoming stiif and dry. This small auxiliary reservoir also furnishesanv immediate supply for the flow of ink to the bristles when the brushis put to use.

Surrounding the bristles and servingV to 4hold them in positiongwithrespect to the remainder of the structure is a conical open ended cap 10having frictional engagement A closure 11 is provided for the lower partof the device, which includes the brisg tles, when the implement is notin use. The

closure 11, like the holder l, Vis preferably.

formed from a hard rubber substitute.

Having thus fully described my invention, what I claim as new and desireto secure byv Letters Patent is Y l. A fountain brush for making smallcharacters, comprising a mainink reservoir, an auxiliary ink reservoir,means for conducting the ink from the main ink reservoir to theauxiliary ink reservoir, bristles carried by said auxiliary reservoir,and means for conducting the ink from the auxiliary ink reservoir tosaid bristles, both of said conducting means comprising elongated tubeshaving valveless conducting openings of minutecross sectionwhereby'unobstructed communication between the reservoirs and bristlesis maintained for keeping the bristles in moist condition.

2. In a fountain brush, a holder 'having a flexible ink reservoirtherein,V a Vtube Seeuredto the lower end of said ink reservoir anddetaohably connected to said holder,

an auxiliary ink reservoir communicating with said tube, a conductingtube extending into one end of said auxiliary reservoir and having anarrow opening-thereinto, bristles ilia-iy ink reservoir.

In testimony whereof I aix my signature.
